Calculus Summer Packet

1 Calculus Summer Packet Congratulations on reaching this level of mathematics in high school. I know some or all of you are bummed out about having to do a summer math packet; but keep this in mind: we want you to be successful. The most difficult thing outside of the calculus is having to recall and apply all math skills you have developed so far. Many of the calculus rules we will learn this year are straightforward and easy to apply, but it is the reducing of solutions or improper algebra skills that will trip up some of you. It is etremely important that students entering calculus have a strong foundation in algebra, geometry and functions. Most questions in this packet were included because they concern skills and concepts that will be used etensively in calculus. Others have been included not so much because they are skills that are used frequently, but because being able to answer them indicates a strong grasp of important mathematical concepts and more importantly the ability to problem-solve. In this packet, you will find the following: Algebra Geometry Algebraic Functions Transcendental Functions Trigonometric Functions Graphing Skills This packet will be collected on the first full day of school. It is etremely important for all students to review the concepts contained in this packet and to be prepared for an assessment of these prerequisite skills to take place within the first week of school. (Date to be given on first full day of school.) I believe each of you is capable of success, but I want you to be fully certain of the epectations and be ready to give your best effort all year. Whether you are taking AP or not, my goal is to prepare you for college calculus and for you to fully know and be able to eplain all calculus concepts and methods. Please do not hesitate to contact us if you have questions this summer. Coach Swagart jswagart@baysideacademy.org Ms. Rollin hrolin@baysideacademy.org Special note for AP Students: Prerequisites according to College Board for AP Calculus Before studying calculus, all students should complete four years of secondary mathematics designed for college-bound students: courses in which they study algebra, geometry, trigonometry, analytic geometry and elementary functions. These functions include those that are linear, polynomial, rational, eponential, logarithmic, trigonometric, inverse trigonometric, and piece-wise defined. In particular, before studying calculus, students must be familiar with the properties of functions, the algebra of functions and the graphs of functions. Students must also understand the language of functions (domain and range, odd and even, periodic, symmetry, zeros, intercepts and so on) and know the values of the trigonometric functions of the numbers 0, π, π, π, π and their multiples. 6,
